missing wifi network after update to 22.04

[Krister Swenson]

I have a Qualcomm Atheros AR93xx Wireless Network Adapter (rev 01) which I've been using for years on my machine without a problem. I just updated to Jammy and I no longer see my wifi network (all my other computer are using it). It was the network that I used to download the update (updated from 20.04).

I do see a ton of networks, however, using wavemon or nmcli, and can use my phone hotspot without a problem.

I haven't found any alarming entries in /var/log/syslog.

Please let me know if I can help debug this.

Could this be related to https://bugzilla.kernel.org/show_bug.cgi?id=215703 ?

[Krister Swenson (thekswenson)]

I reconfigured my wifi network to use WPA2-EAS instead of WPA1/WPA2 - AES/TKIP and the network appeared again.

[Krister Swenson (thekswenson)]

I assume that there is a reason why the old encryption doesn't work (although it did work with my other machine using the same kernel), so I'm closing this bug.
